Two cars got an oil change at the same auto shop. The shop charges customers for each quart of oil plus a flat fee for labor. Th
maw [93]

Answer:

Step-by-step explanation:

Let x = the fee and let y = the cost per quart of oil

x + 5y = 22.45

x + 7y = 25.45     Multiply this equation by (-1) and add it to the 1st equation

 

-x -7y = -25.45

x + 5y = 22.45

     -2y = -3

        y = $1.50 /quart

 

x + 5(1.50) = 22.45

     x + 7.50 = 22.45

                 x = $14.95   is the basic fee

In the diagram, AB is parallel to DE. Also, DE is drawn such that the length of DE is half the length of AB. If sin A = 0.5, the
weqwewe [10]

Answer:

Sin E=0.50

Step-by-step explanation:

Here we are given that DE || AB, and DB and AE are traverse lines to them meeting at point F.

By the properties of parallel lines intersected by a transverse we know that the alternate interior angles are equal.

If we extend DE and AE on both sides , we can see that A and E are equal as they forms alternate interior angles.

Hence

A=E

Sin A = Sin E

0.50=Sin E
